AMD equips the ATI Radeon HD 2900 XT with 320 stream processors to take on NVIDIA?s GeForce 8800 GTS, which features 96 stream processors. However, AMD and NVIDIA have taken different approaches towards their unified shader designs. AMD pairs the R600 GPU with 512MB of GDDR3 memory clocked at 1.65 GHz across an eight-channel, 512-bit memory interface. In comparison, the NVIDIA GeForce 8800 GTS features 640MB of 1.6 GHz GDDR3 memory on a 320-bit memory interface.
AMD equips the ATI Radeon HD 2900 XT with a dual-slot, blower-type heat sink. Unlike the OEM Radeon HD 2900-series previously pictured, which is an 11.5? long card, the ATI Radeon HD 2900 XT makes use of a smaller cooler so everything fits within the 9.5? PCB. Although the R600 GPU supports HDMI audio and video output, the our reference design only features dual dual-link DVI. Onto the benchmarks, the tests were conducted on an Intel D975XBX2 BadAxe2, Intel Core 2 Extreme QX6700 and 2x1GB DDR2-800 MHz. The operating system on the test system was Windows XP, with a fresh install before benchmarking each card. Testing of the AMD ATI Radeon HD 2900 XT was performed using the 8.361 Catalyst RC4 drivers, while the GeForce 8800 GTS used ForceWare 158.19 drivers.
